Application 1ed August 11, 1913.- Seral No. 784,221.

To all whom it may concern.'

Be it known that I, GLENN P. WHITE, a citizen of the United States,residing at Ashtabula, inthe county of Ashtabula and State of Ohio, haveinvented a new and useful Inclinometer, of which the following is aspecication.

The device forming the subject matter of this application is a combinedlevel and plumb, of that general type in which the level vial isreplaced by a counterweighted pendulum. j

One object of the invention is to provide novel means for suspending thependulum.

Another object of the invention is to pro` vide novel means whereby thepointer may be adjusted on the pendulum.

Another object of the invention is to provide a device of this typehaving scales, the construction of the pendulum being such that the samewill coperate readily with the scales.

lVith the above and other objects in view which will appear as thedescription proceeds, the 'invention resides in the combination andarrangement of parts and in the defvr tails of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the in` vention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

In the drawing: Figure 1 shows the invention in side elevation appliedto a level stock; Fig. 2 shows the invention in side elevation, detachedfrom the level stock, one flange being shown in section; Fig. 3 showsthe invention in transverse section; Fig. l is a fragmental elevation ofthe pendulum, the supporting shaft therefor being shown in section.

The device herein disclosed comprises a body 1 in the form of a block,provided in its forward face with a flaring recess 2 in which is locateda flaring ring 3 inscribed with scales 4. A tapered face plate 5, issecured to one side of the body 1 by means of attaching elements 6 andprojects over the recess 2. A shaft 7 is supported at one end in theface plate 5, the rear end of the shaft 7 being mounted in the back ofthe block or body 1.

Mounted to swing on the shaft 7 is a pendulum 8 of approximatelytriangular form. In the forward face of the pendulum 8 is the ribs andthe shaft.

fashioned a recess 9, the walls of which di-Av I verge. as they extendtoward `the lower edge of the pendulum. In the recess 9 is located apointer 10, the forward end 11 of which is inclined and is adapted tocoperate with the scales 4f, the rear or inner end of the pointer 10being rounded as indicated at 12,

to itin the rounded rear portion of the recess 9. A securing plate r14extends across the recess 9 and binds upon the vpointer 10 to hold thesame in place, the plate 14 being held by securing elements 15 whichenter the pendulum 8. f

Although vided for lessening the friction of the penany suitable meansmay be prof dulum 8 on the shaft 7, thependulum is inl 'g the presentinstance shown as provided with a transversefopening 16. Annular ribs 17project from the pendulum into the opening 1G, the ribs 17 being oftriangularv form so as to` present knife edges. lf` desired, thecentral'portion' of the shaft 7 which is engaged by the ribs 17 maybe-of triangular cross section as indicated at 18 and as shown,v

vmost clearly in Fig. 41.*- The 'spaced'circu'm- 4ferential ribs 17define, within the contour of the pendulum, as clearly shown in Fig. l3,a chamber in which a few drops of oil may be placed, to lubricate thependulum as the latter swings upon the shaft, the ordinary handling towhich a device of this type is subjected being sufficient to bring theoil into contact with the engaged portions of struction, the amount offriction between the pendulum and the shaft 7 is reduced lto a minimumand the pendulum will swing freely.

The body member 1 may be attached `in any suitable manner to a tool ofany ksort used in carpentry or in joiner work. In the present instance,however, the body 1 isv shown as counter-sunk into, a level stock 20,the body including flanges 19 whichl are counter-sunk into the loweredge of the level stock. Vhen the device is mounted as above described,although this mounting is not mandatory, a plate 21 may be secured tothe forward face of the level stock 20 and be held in place by screwsl22 or other elements adapted to a like end, the plate 21 being providedwith openings 23 throughy which the scales l and the pointerv arevisible.

When it is desired to adjust the position Owing to this con of thepointer l0, the screwsl which pass through the securing platelt areloosened, and thus the pointer may be shiftedlaterall7 in the recess 9until the. desired adjustment is obtained, the rounded rear end 12 ofthe pointer l0 fitting into the rounded rear or inner end of the recess9 during the adj ustingoperation.

rlhe scales may be graduated inany desired manner, and will be founduseful as vvillibe. obviousfto those skilledin theart. Owingvto thefact'that the scales are,in scribed upon Ythe :flaring ring .3, the;Scales will be risible at alltmes andfmey belreed Without deulty Having'thus described ,the invention, what is elamedas ,1- 111 a devieeefthefelesedeseribed, e body ma pendulummeunted werving in'l the bedr; agraduated v:Allee/m12.er carried by the body. andi having Aict-Sgneduated surfaee i11- ter'seetiagthe .plane ef-Swingingfmevemem of thependulum; a pointer movable k upon thependulum radially of thependulumto adjust the fgdstance between the indicating end ef the penterfandSaid greduatedosur face, i ,the 'pointer being movable circumferentiallyof; the pendulum to adjust the indicating endof; the, pointer `with,respectI to the graduations ofthe said membem and a clamping Emeansengaging the pendulum andy the pointer, theipenter-beng'movable withfre'spectfto vthe clamping means both movement o f the pendulum; apointer located in the recess and adapted to coperate with saidgraduated surface; a plate eX- tended; across tli .er e`ces s andengaging the pointer and a securing, element uniting the plate withtliependulum; the inner end of the pointer being leeeelymeiinted intherecess 4te y permit .the Reinier f te be ediueted both longitudinallyand transversely when f the plate is loosened.
